Gaseous Fire Suppression - Theory

Theory

There are four means used by the agents to extinguish a fire. They act on the "fire tetrahedron":

  • Reduction or isolation of fuel
No agents currently use this as the primary means of fire suppression.
  • Reduction of heat
Representative agents: HFC-227ea (MH227, FM-200), Novec 1230, HFC-125 (ECARO-25), FS 49 C2 .
  • Reduction or isolation of oxygen
Representative agents: Argonite / IG-55 (ProInert), CO2 carbon dioxide, IG-541 Inergen, and IG-100 (NN100).
  • Inhibiting the chain reaction of the above components
Representative agents: FE-13, FE-227, FE-25, MH227, FM-200, Halons, Halon 1301, Freon 13T1, NAF P-IV, NAF S-III, and Triodide (Trifluoroiodomethane).

Famous quotes containing the word theory:

    “The theory of truth is a series of truisms.”
    —J.L. (John Langshaw)

    “No theory is good unless it permits, not rest, but the greatest work. No theory is good except on condition that one use it to go on beyond.”
    —André Gide (1869–1951)

    “There never comes a point where a theory can be said to be true. The most that one can claim for any theory is that it has shared the successes of all its rivals and that it has passed at least one test which they have failed.”
    —A.J. (Alfred Jules)
